  • Title: The influence of daily activity on ambulatory blood pressure.
    Author: Pickering TG.
    Journal: Am Heart J; 1988 Oct; 116(4):1141-5. PubMed ID: 3177189.
    Abstract:
    Studies of ambulatory monitoring of blood pressure have found that blood pressure shows large variations over a 24-hour period and that in many subjects clinic pressures are a poor guide to the level of pressure at other times. Many of the variations in blood pressure that are observed during a normal day are predictable and can be attributed to factors such as physical activity, the sleep-wakefulness cycle, eating and drinking, and mental stress. In general, hypertensive persons show patterns of change similar to those of normotensive persons, but their diurnal profiles of pressure are reset at a higher level.
